- Аннотация: A comparison between differentfield-assisted sintering methods (FAST), namely Spark Plasma Sintering (SPS)andflash-sintering (FS), is reported for calcium and alkaline phosphates especially with regards to their micro-structure. A reduced average grain size upon SPS is shown when pressure is decreased. Shrinkage curves duringflash sintering are compared with similar conventional sintering curve. Flash sintered ceramics possess unusualmicrostructural features, including a density/grain size gradient where the surface of the specimen is denser andpossesses a coarser grains with respect to the core. Such microstructural gradient is opposite to what generallyobserved, the surface being colder due to the heat radiation toward the environment. The change in the averagegrain size for each sintering method is related to the process parameters.
